Thermal insulation aluminum doors and windows, using thermal insulation bridge broken aluminum profile and hollow glass, with energy saving, sound insulation, noise prevention, dust prevention, waterproof and other functions. The heat conduction coefficient K value of the bridge cutoff aluminum doors and windows is below 3W / m2 · K, which is half of the heat loss of the ordinary doors and windows, about 30% of the heating cost is reduced, and the sound insulation amount is more than 29 decibels, with good water tightness and air tightness, all of which meet the national standard for class A1 windows.
Reduce heat conduction: the heat conduction coefficient of the thermal insulation bridge cutoff aluminum alloy profile is 1.8 ~ 3.5W / ㎡ · K, which is much lower than that of the common aluminum alloy profile 140 ~ 170W / ㎡ · K; the heat conduction coefficient of the hollow glass structure is 2.0 ~ 3.59w/m2 · K, which is much lower than that of the common aluminum alloy profile 6.69 ~ 6.84w / ㎡ · K, which effectively reduces the heat conduction through doors and windows.
Prevent condensation: the temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, reducing the possibility of indoor moisture condensation on the profile surface due to supersaturation.
Energy saving: in winter, the window frame with thermal insulation strip can reduce 1 / 3 of the heat lost through the window frame; in summer, if there is air conditioning, the window frame with thermal insulation strip can reduce the energy loss more
Environmental protection: through the application of thermal insulation system, energy consumption can be reduced, and environmental radiation caused by air conditioning and heating can be reduced. ⊙ good for health: heat exchange between human body and environment depends on indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of doors and windows, the temperature is no less than 12 ~ 13 ℃, which has reached the most comfortable environment.
Reduce noise: adopt hollow glass structure with different thickness and insulated bridge cutoff aluminum cavity structure, which can effectively reduce the resonance effect of sound wave, prevent the transmission of sound, and reduce the noise by more than 30dB.
Colorful colors: aluminum profiles of different colors can be produced after anodizing, powder spraying and fluorocarbon spraying surface treatment. After rolling and combination, the insulated aluminum alloy doors and windows will produce two-color windows of different colors indoor and outdoor.
